Well, as you can tell from my handle, I live just outside DC in the Virginia suburbs.
There are many resources for the homebrewer in our area. We have our own on-line HBS, Jay's Brewing. Jay used to operate store hours out of his basement, but sadly the zoning board in Fairfax has asked him to stop. He has complied, but still offers great selection and prices through his website, and will even save you on shipping by dropping the supplies off at your place! Please, think about patronizing his place in addition to the larger on-line homebrewing websites. It's worth it.
There are also a number of homebrewing clubs around here:
Northern Virginia Homebrew Club
Gaithersburg Area Brewers
Hope this is helpful!
